对高一学生的元认知水平和化学键概念形成情况进行调查,通过数据分析得出以下结论:元认知水平与化学键概念形成之间存在显著性相关;两者的相关程度离子键概念较为显著;元认知监测性水平对化学键概念影响最大,元认知总结性水平影响最小.基于此,提出增加化学键可视化途径,提高学生元可视化水平;在化学键教学中使用自我提问单;设置阶梯型问题,利用前概念对化学键进行教学;调整化学键教学顺序等教学建议.

Thispaper investigates the status of first-year students' metacognitive level and chemical bond conceptualization through data analysis. The results show that: there is a significant positive correlation between metacognitive level and chemical bond conceptualization; the correlation degree is more significant in covalent bond concept than in ionic bond concept; and effects of metacognitive sub-levels on the chemical bond conceptualization are identical. It, therefore, suggests such concrete steps as increasing the visualizing approach of chemical bond to improve students' metacognitive level by using self-questioning sheet in teaching, setting the ladder-type problems to make use of pre-concepts, and adjusting the order of chemical bond teaching.
